ACHERON DESIGNER SCREEN CHANNEL 
LOUDSPEAKER

At the heart of Meyer Sound's EXP line of cinema products 
are the Acheron

®

 high-performance screen channel loud-

speakers. The Acheron Designer is the most compact of the 
Acheron models, making it an excellent choice for sound 
design suites, screening rooms, private theatres, and small 
commercial theatres. Optimized for installation behind per-
forated screens, the Acheron Designer combines the advan-
tages of self-powered technology and innovative horn 
design to deliver exceptional, precise coverage for the left, 
center, and right screen channels for cinema.

The Acheron Designer uses the same patent-pending horn 
technology and high-frequency compression driver as the 
other Acheron models, delivering the same 38 Hz to 17 kHz 
frequency response. This consistency of fidelity between 
Acheron models ensures that soundtracks monitored with 
the Acheron Designer translate accurately when played 
back in larger rooms with the Acheron 100, Acheron 80, 
Acheron Studio, or other calibrated cinema system.
